  28  * TYPO3 Backend initialization
  29  *
  30  * This script is called by every backend script.
  31  * The script authenticates the backend user.
  32  * In addition this script also initializes the database and other stuff by including the script localconf.php
  33  *
  34  * IMPORTANT:
  35  * This script exits if no user is logged in!
  36  * If you want the script to return even if no user is logged in,
  37  * you must define the constant TYPO3_PROCEED_IF_NO_USER=1
  38  * before you include this script.
  39  *
  40  *
  41  * This script does the following:
  42  * - extracts and defines path's
  43  * - includes certain libraries
  44  * - authenticates the user
  45  * - sets the configuration values (localconf.php)
  46  * - includes tables.php that sets more values and possibly overrides others
  47  * - load the groupdata for the user and set filemounts / webmounts
  48  *
  49  * For a detailed description of this script, the scope of constants and variables in it,
  50  * please refer to the document "Inside TYPO3"
